Kuyini urea njengendlela umquba. Urea (Umanyolo): Imiyalelo

Abalimi abaningi, balimi kanye abatshali namuhla abakwazi ukucabanga ukuthi kungenzeka kanjani ukuba benze ngaphandle umquba. Ngenxa ukuvundiswa ehlangene, isitshalo ukukhula evuselela ukhule ngokushesha, ukwakha amahle, amahlamvu aluhlaza, uhlelo strong impande, ngaphansi zichayeke ezifweni. Kulokhu, into esemqoka - Ungeqisi it futhi azi kahle ukuthi umuntu Umanyolo ofanele ke ukuba angabi lezimanga ezingemnandi.

Kuyini urea?

Urea njengo manyolo asetshenziswa kabanzi ukunika amandla ukukhula, ukukhiqiza izitshalo obuningi, ukugcinwa izitshalo zisesimweni lemukelekako. I-nitrogen ibaluleke njengendlela yemifino kanye nezitshalo Ornamental. Kuyinto ekhona amaprotheni futhi ikhuthaza ukukhula ngesivinini. Nge ukuntuleka nitrogen isitshalo ukunikeza kancane amahlumela, iingojwana amahlamvu mancane, amancane, umbala ukukhanya oluhlaza noma aphuzi. Flower efihlekile angawa off, izithelo hhayi esigaxe.

Kuyini urea? Njengoba Umanyolo isetshenziswa ukusebenzisa kwangasese. Urea kakhulu bagxila, ukubunjwa yayo iqukethe cishe angu 45% i-nitrogen. It kungenziwa ngokuthi Umanyolo jikelele, efanelekayo bonke hlobo of mila. Ngokubukeka kuba ubuhlalu esobala noma elimhlophe luyimbudumbudu, encibilikayo ngokuphelele emanzini futhi abanalo iphunga. Y urea kungase kwandise hygroscopicity umswakama ephakeme. Isetshenziselwa avale phezulu ngoba izitshalo kokungathathi hlangothi nenhlabathi urea (Umanyolo).

Iziyalezo yokusetshenziswa

Urea ingasetshenziswa zonke izinhlobo zenhlabathi, ngisho amanzi-ngemvume, ngoba iqinile kahle inhlabathi hhayi sihlanziwe inhlabathi ezifana ammonium nitrate. Urea isetshenziswa kokubili ukuze avale phezulu, nomanyolo eziyisisekelo. Ukuze izitshalo yemifino urea tingentiwa ngaphambi kokutshala kanye kokukhulelwa ngesikhathi yokukhula e umthamo 5-10 g ngalinye 1 m ^2. Ngaphambi zom kudingekile ukuba uthele isixazululo 50 g ngalinye 10 amalitha amanzi, ukugeleza okuyisibonelo - 3 L / 100 m ^2. Ukuze nezihlahla zokuhlobisa kanye nezithelo izihlahla kungaba urea ukusuthisa ngqo emva zom futhi aphinde mayelana isixazululo inyanga 30 g / 10 l yamanzi.

sokuphuzisa urea

Njalo Umanyolo has izici zayo siqu okumelwe icatshangelwe ngaphambi kokuba uyisebenzise uma inhloso yazo. Ammonium carbonate emoyeni ubola ngokushesha kakhulu, kusobala - ebusweni isicelo urea kuyinto ayizwakali. Lokhu kungachithwa imali, ngoba lesi sitshalo ongawamukeli izincwadi ezidingekayo kuye. Farming imikhuba ukutusa ukusetshenziswa urea endaweni phansi evikelwe. Ngemva kokukhulelwa kufanele ngokushesha linamathele emhlabathini, indlela kuphela ukuvimbela ukulahleka ammonia gaseous. Udinga ukwazi ukuthi urea njengoba umanyolo ngokushesha zakhukhula inhlabathi, ngakho indlela engcono kakhulu yokwenza kube ngaphansi impande isitshalo ngesimo isixazululo.

Ukuvikelwa nezitshalo ezokudabuka kwamanye amazwe

Urea isetshenziswa hhayi kuphela ukuze avale phezulu, kodwa futhi njengendlela yokuthola inkathazo. Uma uze entwasahlobo izinsuku efudumele, kanye isixazululo urea okufanele isetshenziswe ulwe izinambuzane ubusika ezifana Boll weevils, aphid, psylla, nabanye. Le nqubo kumele kwenziwe ngaphambi efihlekile ukuvuvukala. Lungiselela indlela yokulawula inkathazo silula, ngoba kufanele buhlanjululwe 10 amalitha amanzi 0.5 amalitha isixazululo kanzulu zomuthi.

Urea futhi livikela izitshalo kusuka nebala onsomi kanye utwayi, sishaye ngenkathi labetibambile ekwindla, lapho amaqabunga ukuthi usanda kuqala iwe. Odinga ukucubungula amahlamvu - efana kwamaqhawe, nokuphela lowo owayephatha oshiywe kwezihlahla notshani. Isixazululo ibhalwe ngendlela efanayo njengoba ukulawula izinambuzane eziyinkathazo.

efaka umquba houseplants

Kasibili zonke izitshalo zidinga ukuvundiswa, kodwa udinga ukuthi ucabange kabili ngaphambi kokusebenzisa ibhekwa njengoba urea (Umanyolo) izilwane ezifuywayo oluhlaza. Isicelo izitshalo zasendlini nitrogen kuyadingeka ngoba ikuvumela ukudala umqhele omuhle kakhulu, ukusheshisa ukukhula, ukuvimbela ukuwa yellowing kanye leaf. Urea kakhulu bagxila, ngakho ukusebenzisa kwayo kufanele wasondela ngokuqapha okukhulu. Uma ezokuzwisisa umthamo, kungenzeka ukuba silahlekelwe yiyo isilwane sakho, noma zichithe ukubukeka kwakhe.

Kufanele kuqondwe ukuthi lokhu urea. Njengoba Umanyolo kufanelekile udala aluhlaza, amahlamvu aluhlaza. Futhi eziqhakazayo, nitrogen akuyona njengoba ewusizo, ngoba kubambezela insalela ihlumela kumiswa inqubo. Ama (hyacinths, Hippeastrum), ukhuni (amawolintshi, umkhiwane ungakhahleli, ulamula), esigaxeni (irises, calla iminduze) kusukela ngezinsuku zokuqala zokuphila abadinga nitrogen ephezulu sigqoka, ukuze bakwazi avundiswe urea ngaphandle ukwesaba. Kodwa tuberous (Caladium, Gloriosa) kudingeka bondliwe ngemuva ukubonakala amaqabunga yokuqala. Urea njengendlela nomanyolo for houseplants esetshenziswa njengoba isixazululo. Kusho ukulungiselela izinga 20 g ngalinye 10 amalitha amanzi, kwanele 10 m ^2.

Ukondla ngoba zemifino nezithelo izitshalo

Urea Umanyolo kufanelekile cishe zonke izinhlobo zezitshalo, kuyaphumelela ikakhulukazi sokukhula vegetative. Nokho, phawula ukuthi izitshalo ezahlukene kumele bagxila degrees ezihlukahlukene, njenge urea umquba. Isicelo garlic, onion, iklabishi, amazambane, upelepele notamatisi kungenzeka nganoma lokuhlushwa-20 g urea m ^{2 ngalinye.} Ngaphansi ipea and ikhukhamba owethulwa Umanyolo ngalinye 7 g / m ^2.

Utamatisi, strawberry, iklabishi ikhukhamba ingakwazi ngezikhathi ukondla isixazululo 25 g / l, futhi yehlise ngo urea lokuhlushwa kabili ngaphambi ihlumela break kuyinto uthele gooseberries, currants kanye nezinye ezihlabayo izithelo kanye berry. Urea kunomthelela nomqhele omuhle, ngakho-ke Kunconywa ukuba enze ngaphansi apula izihlahla (230-250 g), ali cherry (110-150 g). Urea kungaba ahlakaze phezu kahle, bese uthele kahle ngamanzi. It bavunyelwe futhi efaka umquba isixazululo, kodwa ukubekela eceleni ngenkasa engenakwenzeka.

Uma uqhathanisa nabanye urea umquba nitrogen, ezifana ammonium nitrate, ikakhulukazi uyazuza: esiphezulu ukukhula akhuphula, efanelekayo isicelo foliar kanye at lokuhlala evamile akazange ashise amahlamvu. Ukuzisebenzisa kahle urea akugcini nje kuthuthukisa ukubukeka izitshalo, kodwa futhi kukusiza ukuba aqiniseke ukuthi uthola isivuno ocebile.
